Balloon folding control mechanism

A balloon catheter comprising:

• a inflatable balloon comprising a balloon wall defining an interior volume, the balloon further comprising a distal end, a proximal end, and a central portion disposed therebetween;
• a catheter comprising an elongated shaft extending along a longitudinal axis between a distal end portion and a proximal end portion, the proximal end portion comprising a connector configured to engage an inflation device, the distal end portion fixedly connected to the proximal end of the balloon, and a lumen extending though the shaft and in fluid communication with the interior volume of the balloon;
• an end cap fixedly connected to the distal end of the balloon;
• a stiffening member extending distally from the distal end portion of the catheter and through the interior volume of the balloon, the stiffening member being engaged with the end cap;
• and
• a balloon folding control mechanism configured to promote refolding of the balloon into a predetermined folding configuration upon deflation of the balloon.
